PHONOGRAPH.

Application filed May 24,

This invention relates to automatic phonographs, and more especially to phonographs of the general type including a multiplicity of record-carrying tables, such for instance, as are shown in my Patent Number 1,168,606, dated January 18, 1916, and in my allowed application Serial Number 577 ,32 1, filed July 25, 1922, for automatic multiple record phonographs.

The principal object of my present invention is to provide improvements in the driving mechanism, and more particularly to provide-a combined multiple table phonograph and induction meter type motor all 1n one organized structure in which the motor is provided with an armature ring presented and running in juxtaposition to induction coils.

Another object is to provide means for readily varying the number of rotations of the record-carrying tables without changing thespeedof the motor armature. Another object is to provide a multiple table phonograph in which means are provided for progressively shifting the tone arm and the sound box'from one applied record to an other, and to provide amotor including a rotary element operative to selectively drive the respective tables and also to drive a mechanism operative to swing the tone arm from table station to table station. An object is to provide means for defining the position of the tone arm accurately as to records of the usual standard sizes, and, in this connection, an object is to provide means for preventing a reverses winging of the tone arm accidentally or otherwise from its properly disposed position preparatory "to the stylus being engaged by a contiguous record An object is to provide an improved means for rendering the tone arrncarrier inoperative so that any one of the turn-tables may be continuously rotated for any desired length of time, and without a swinging. of the tone arm from table to table.

Other objects and advantageswill be made manifest in the following specification of an embodiment of the invention illustrated in the accompanying drawings, wherein- V Figure 1 is a plan of the improved phonogr Flg. 2 1s a side elevat on and vertical section (substantially full size) of the tone arm,

In the machine of my present invention, phonograph records, here shown as discs D, are adapted to be mounted on turn tables which are adapted to be rotated substantially at a uniform rate of speed, and yet provide means for automatically interrupting the operative engagement between a disc D and the stylus S according to the size of the record disc and according to the length of its record groove. The means for determining the operative co-action between a disc D and the stylus includes a two-speed gear mechanism selectively operative to drive the means for lifting a record disc to engage the stylus of the .tone. arm T;'

said means including a member which is designed to move at a given rate when, a large disc is being played, and to move at a faster rate when a small disc is being played, since the smaller discs require an appreciably shorter length of time-while they are engaged'by the tone arm stylus than do the larger discs.

The invention is shown as embodied in a machine having a plurality of, vertical spindles 2, which are appropriately journaled in bearings 3 and 4, which may form a paft of a skeleton frame structure, the va-' rious portions of which are designated at 5; the frame components being of substantially cylindrical form and including upper and lower ring portions which are connected as by webs 5. j The' spindles extend substantially vertically and each is pro vided with a turn-table 6; the spindles be ing arranged in a common circle and designed to rest upon contiguous bearings, so that the tables are, when at rest, in as common plane, and the tables are designed to receive, in the usual manner, phonographic record discs D which, forthe purposes of the present exposition, may be considered as of ten and twelve inches diameter in difl erent sizes. a

Arranged in the geometrical center of the group of turn tables is a vertical tone arm column 7, which is appropriately secured in the frame, and this has, at its upper portion, a suitable bearing to receive the contiguous end of the tone arm T which carries the sound box B; the tone arm beinfg the top of the column 7 to eely swing around the same, and being also pivoted upon a horizontal, transverse axis on a swinging spider 7", so that the outer end of the pivoted ondriving member 22 1s operating, as willrbe tone arm may be raised and lowered in a manner to be subsequently described. The column 7 forms a continuation of the sound tube leading to any horn or other amplifying outlet chamber, not here shown.

The tone arm T is provided with a downwardly extending leg-8, which has at its lower end a substantially radially project- .ing foot 10 and a rounded heel 9 which is normally supported on the top of a rotat ing carrier 12, surrounding the column 7 and rotating thereabout. The carrier 12 is in the form of a plate or flat ring and is fixedly attached to a gear 13, disposed be-' low the. carrier 12 and resting on and countersunk in the frame part 5.

Extending from the top bearing portion 5, Figure 5, is a vertical bearing 15', in which there is disposed a shaft 16, to the upper end of which is secured a pinion 17, which engages an intermediate gear 18, meshing with and driving the carrier gear 13. The shaft 16 is provided with an upper gear wheel 16, meshing with a gear 20, forming a portion of or secured on a sleeve 21, upon the wer end of which is secured an element whic in the. present case, forms a rotorarmature'including the hub 22, secured on the sleeve 21, and a peripheral 'flat armature ring 22*; this element constituting the prime driving, motor element of the mechanism.

Also secured on the sleeve 21, which substantially constitutes the motor shaft, is-a gear 23, of larger diameter than the gear 20, and engaging a gear 24:, of smaller diameter than the gear 16, and which is loosely mounted on the lower end portion of'the shaft 16. Means are provided for selectively coupling either gear '16 or 24 to the shaft- 16, and this means includes a clutch collar 25, splined on the shaft 26 and the ends of which are adapted o engage complementary clutch portions 5', on the gear 16*, and 25 on the gear 24, sothat the shaft 16 can be'driven at either of two speeds.

The rotor-armature is shown as provided with an anti-friction, lower end bearing 32, surroundingan' inner hollow shaft 29, on which the hollow motor shaft 21 is loosely at its upper end with a worm wheel 28, and

this is constantly in mesh with a worm' pinion 27, formgd with or provided on a worm shaft 27 horizontally journaled in a bearing portion 5 below the carrier plate 12, and being provided with a bevel pinion 27 engaging and being driven by a bevel pinion 16, secured on the upper end of the shaft 16. 4

Therefore, when the rotor-armature or hereinafter described, it drives the selected gear 16 or 24 and this, in turn, drives the shaft 16 whlch, therefore, concurrently III drives the carrier 12 at'a very slow rate of movement, and also drives the worm wheel 28 and the inner, hollow shaft 29. a

The hollow shaft 29 passes through and forms a. bearing for the sleeve 21, and on the lower end of the hollow shaft there is secured in any suitable manner, as by threads 29, the hub 30 of a tripping device which, in the present form, includes a sector plate 3]., Figure 6. On the hub 30 is provided the anti-friction bearing 32, and upon this rests the hub of the rotor-armature 22 of the sleeve 21.

The rotor armature'is provided with a horizontally arranged, turn-table, driving rim or face 34, of any suitable construction, andwhich preferably is of an efficient friction producing element such as a band or ring of leather or rubber. This driving ri n34 is for the purpose of forming a common driver for the driving wheels 2 of each of the turntable spindles 2, when the spindles are elevated so as to bring the friction wheels2 against the driving rim 34.

The various record turn-tables adapted to be raised from a normal position in a common planeto an effective, raised position to lift the records successively into engagement with the needle or stylus in the sound box. The tone arm and the sound box move constantly in a fixed, horizontal plane, while being supported by the rotating carrier '12.. However, it is possible to, lift the tone arm on a horizontal axis during the-operation of the parts.

The tone arm carrier'rotates at a given rate of speed so as to swing it from one disc to another in ample time to be. positioned above the disc on each table before the table is elevated. Since it is possible .to utilize two sizes of'discs D onthe tables,

it is necessary to provide means for accurately defining the stopping position of the'tone arm at predetermined locations, s'b that it will properly register with the starting curve of a disc ofleither size. To that end, my present invention includes an improved form ofpositioning means.

In this machine, there is disposed upon the top, central portion of the frame and below and projecting beyond the edge of the carrier 12, an ad ustable arrester inthe form of a flat ring 4 0 provided with a set of upwardly projecting lugs or dogs 40, which are arranged in a common circle on the top of the arrester ring v and so disposed as to stand in the pathof the outer or toe end of the foot portion 10 of the tone arm leg 8, which is designed to successively engage the fixed dogs 40 as the tone arm isswuug around by the carrier in the direction of the arrow thereon, Figure 12. The arrester ring is designed to be turned on its own axis so that the dogs40 will 6 are arrest the tone arm in an outer position as to the table center to properly engage the starting record groove of a twelve-inch record, and is also adapted to be adjusted so that the dogs 40 will serve to arrest the swinging movement of the tone arm by the carrier 12 to properly position the sound box stylus at the starting groove of a smaller or ten-inch record. To that end, the arrester 40* is shown as provided with a radially extending fork 40 to receive a segmental cam 41, which is secured on a setting stem 42, Figure 4, journaled in an arm of the frame 5 and having at its-upper end a readily accessible thumb wheel 43, by which it may be turned to rotate the arrester according to the size of records to be played.

a position in its orbit as to arrest the tone arm to position the needle of the sound box over the starting groove of a twelve;- inch record; It is understood that all of the records positioned at one time on the machine must be of equal size. When playing small records, the setting stem 42 is.

shifted so as to .throw the arrester and the dogs 40 through a small are about the center of the tone arm and arrester to a position whereat the dogs 40 willpermit the tone arm to swing nearer to the centers of the turn tables and thus be properly positioned to start the playing of small records. The arrester ring 40 is shown as provided with a slot 40, into which projects a stop-pin 4O to limit the movement in either direction of the arrester. The adjusting cam 41 may be stopped as by a stop pin 45, Figure 13.

For the purpose of preventing a backward swinging of the tone arm from its raised position against a stop lug or dog 40, as the tone arm may be lifted, there is disposed adjacent each of the dogs a backstop or rest 46, spaced just sufficiently from the dog to receive the projected and uplifted toe end of the foot 10, as is clearly shown in Figure 2; the backstops 46 beingof a height slightly greater than the dogs over which the foot portion is adapted to move as the tone arm is automatically swung in toward the center of a disc which is cooperatively engaged for a playing period. i

The setting stem 42 provides means not only for adjusting the arrester 40", but it also provides means for shifting the gear shift or change device 25. I On the lower end of the setting mm 42 is secured a screw 'or'provided a threaded portion 47, upon .which is slidably mounted'a hub 48 of a clutch shift arm 49, the opposite end of which engages'the clutch member 25. The

hub is shown as provided with a pin or 1011p or down and the clutch member is 4 arranged cam setting correspondingly shifted so as to lock one or the other of the gear Wheels 1624.to

the countershaft 16.

This change speed device provides for the change of speed of the quadrant 31, which forms a part-of: means for timely elevat.

ing the successive turn-tables. a

The .tables are elevated-in the following manner: The lower end of each spindle 2 is designed to bear against a cam including a rail of segmental form having an elevating, leading cam or inclined face 50,. This cam rail, in my present invention, is mounted'for pivotal action adjacent its forward cam end 50 on a pivot pin 51, provided on the cam sector 31, and its rear end portion is yieldingly drawn inwardly, on top of the sector 31, as by a' spring 52. The cam sector 31 is substantially continuously driven in the direction of the arrow thereon in Figure 6, and the cam rail 50 is adapted to be swun from a retracted position to an outer, e ective or set positionat predeter mined intervals during its orbital movement, and for thus shifting the cam rail 50 outwardly and to a substantially concentric position as to the axis of the tone column, a portion of the cam; rail 50 has a shoe 50 with an inclined leading end 50, which is designed to be successively brogght into engagement with stationary cam" tting means which may consist of a simple and substantially downwardly projecting or otherwise tongue or lug 53,- Figures 6 and -11, and of which there are as many as there are turn-table's or turntable stations in the machine.

Thus, as the cam'sector-31 slowly sweeps in "its horizontal orbit, the shoe end 50 engages an interposed, stationary setting tongue 53, and the cam rail 50 is thrown to the outer, effective, concentricposition .so as to be dis osed below and-pass under, engage and liiiza turn-table spindle 2; the approaching position of the cam being indi-' cated clearly in Figure 7. Upon co-action or engagementbetween the lifting cam rail 50 and the contiguous turn-table spindle 2, thespindle is" elevated and mai ntained in a substantially unvarying position as the top, plane face of the cam 50 continues in its circularorbit, until such predetermined time as may be necessary to trip or interrupt the co-ae'tion between the cam and'the en- .31 is slowly sweeping around:

mined by the length of the record groove on the engaged phono aphic record disc.

Means are provi ed and adapted to be manually adjusted for automatically, relis ably effectively and substantially instantaneously tripping the'cam 50 from an engaged turn-table spindle 2, substantially concurrently with the reaehing of the stylus of the sound box with the end of the record groove, so that the table and record will be withdrawn from effective or elevated, playing position 'and the record disengaged from the stylus. A simple form of cam tripping means is here shown as including a set of radial tripper arms 55, the hubs of which are mounted loosely upon the hub 30 of a cam sector .31, and below the anti-friction bearing 32. Each tripper arm is provided with a segmental gear'56, which issupported for convenience in a groove 57,

provided in abottom ring of the frame 5, as

- clearly shown in Figures 5 and 11.

There is one tripper arm 55 for each turntable. station, and these arms are disposed relatively in advance of the turn-table stations so'that the tripper arms 55 can be properly positioned and cause the tripping of the cam 50 or its withdrawal from the engaged and elevated turn-table stem at the proper moment. Each segmental gear 56 is engaged by a setting wheel 58, secured on a setting spindle 59, for which suitable bearing portions 5 of the frame 5 are provided. The upper ends of the trip setting'spindles 59 are provided with thumb wheels 60, and below these are dials 61, indexed according to any arbitrary system adopted and used to indicate a corresponding index applied to the various record discs according to the terminating position. of the record groove. Having a given record groove index, it is only necessary to set the indicating spindles 61 -with respect to any suitable index mark position by the engaged setting tongue 53,

the camshoe L 5O", WhlCll has 'an'arcuate, in-

,ner edge, passes freelyalong the outside 'of the let-off tongue"55!', while thecam sector W soon-as the tail .end b fth'e shoe 50!. passes the let ofi tongue '55.,- as in- Figurev 6, the!) F the cam retracting spring -52i-instantly1acts to :retract thecam 50 and. pull itzinwardly from supporti ;-relation below; theeir aged=-tum=tabl g spindle 1.2, and the latter gaged turn-table spindle, this being deter-. t 'en drops and brings down with it its re 1' spective table 6, the downward movement of the latter being cushioned and determined as by a cushioning washer 6 Figure 5, when the latter falls to engagement with the upper bearing 3 thereof.

It will be seen that each of. the cam trippingarms can be independently adjusted in direct accordance with the actual length of the record groove on a record applied to a coordinate turn-table. In operation of the machine, the cam 50 is moved to an outer or set position at each turntable station by the reaction of the cam setting tongues 53, and these hold the engaged cam in outer, set position until it is engaged and supported by the let-off tongue 55 of the cam tripping lever arm 55.

The cam 50 is stopped in its inward or retracted positionby any suitable stop, as a lug 31, provided on the top of the cam sector 31.

Any suitable governing means may be employed to regulate the speed of rotation of the turn-tables, and a simple form is shown as including a centrifugal governor 70, having a worm screw 71, engaging the worm wheel or ring 72, formed or secured on a sleeve or hollow shaft 21, in the present case being shown as disposed between the gear portions 20-23. The centrifugal governor is provided with a disc 73, movable toward a brake shoe 75, Figure 9. The brake shoe is shown in Figure 8 as being mounted on a lever 76, connected to a spring 77, suitably attached to a fixed part. The brake lever 7 6 is engaged by an adjusting screw 78, which may be turned to advance the brake shoe toward the brake disc 73 of the governor, and therefore increase the resistance as the "motor reaches a predetermined speed.

The above specificatiomit will be seen, sets forth, first, the operating train, and the several automatically acting mechanisms of the phonograph. A feature of the invention is the provision of a novel prime motor including the rotor-armature 22-22 above re ferred to, which serves as the principal driving means whereby all the turn-tables and other elements of the machine are actuated.

The motor of this machine is of the well known, highly efficient, practicable, simple, and reliably acting induction motor type of motor, in which there are utilized suitable induction coils diagrammatically illustrated as arranged in opposition at and 80*, Figure 15, the coils of each set being spaced to receive the armature ring 22 which operates, therefore, rotatively between the coils of each set in the usual and well known manner of this type of motor. The several sets of coils 8080 are arranged, in the present case, in upright position along the inside faces of the ring components of the frame 5.

It is to be understood that this organized phonographic mechanism and self-coir tained motor are adapted to be'erected as a complete, unitary system, and mounted in any suitable manner in any desired form of cabinet or other support.

The turn-tables operate, when engaged by the rotor-armature, at a substantially constant rate of speed, which is not changeable by the gear shift device including the clutch member 25; the latter being for the purpose of regulating and changing the speed of travel of the cam segment 31 according to whether a large or small disc is being run. If a large disc is being played, then the gear shift is set so that the cam is driven slowly, while if a small disc is being played, the gear shift is set so that the cam will drive faster,

The mechanism of the apparatus is shown in Figure 16 as covered by a top plate 85, and this is provided with a central opening 86, through which is exposed upwardly projecting arrester lugs 10 and 46, so that these will be in efiective position to engage the tone arm foot portion 10. As the tone arm is thrown to the inner position of a record, as shown in Figure 16, the arm is positively limited against an inward sweeping movement across the disc by guards shown as consisting of upwardly extending lugs 87, positioned around the edge of the opening 86 and so disposed as to intercept the toe end of the foot 10 when the tone arm is ele vated to effective "position, and the end of the toe is swinging in a circle in which the stop guard lugs 87 are positioned. As soon as the turn-table is tripped, the tone arm descends until its foot engages the carrier 12, and. in this action, the toe of the foot 10 drops clear of the stop guard 87, as is shown in Figure 17 so that the tone arm can be swung to the nextstation as soon as the subjacent record and turn-table have been lowered; the stylus of the sound box on the tone arm sweeping, in its lowered position, in a i plane above the plane of the normal lowered records.
